The present invention provides novel block copolycarbonates comprising residues from a hydroxy terminated polyetherimide or polyimide, residues from a dihydroxy compound, and residues from an activated carbonate. In a preferred embodiment of the present invention the polyetherimide or polyimide blocks exhibit high Mwhile the resulting block copolycarbonate exhibits a single T. The novel block copolycarbonates of the present invention are produced under melt polymerization conditions in the presence an activated carbonate source.

Phenol and isopropenylphenol are recovered from BPA tars by sparging the fluidized BPA tar while heating in the presence of a basic catalyst. Sparging dramatically increases the efficiency of phenol and isopropenylphenol recovery. Recovered isopropenylphenol may be converted to bisphenol A in the distillate by reaction with phenol and an acidic catalyst.

Catalytic materials including divalent palladium compounds, divalent cobalt compounds and bromide sources such as tetraalkylammonium and hexaalkylguanidinium bromides are removed from organic carbonylation reaction mixtures comprising said materials in combination with diaryl carbonate and hydroxyaromatic compound. The removal steps include extraction with an aqueous complexing solution for palladium, extraction with an aqueous non-basic and preferably ionic extractant for cobalt, and extraction with water to remove bromide source. These steps may be combined into an integrated process. Further steps of recycle of the palladium by reduction to elemental palladium and conversion to a catalytically active species, and conversion of cobalt to a catalytically active species, may be included in the integrated process.
